Installation

tronz is published as a meta-crate that re-exports its sub-crates. Its default feature set includes the TLS gRPC provider, contract support, and the local signer:

cargo add tronz

Or add it to your Cargo.toml directly:

[dependencies]
tronz = "0.5"

tronz is async-first and built on tokio, so you will also want the runtime:

cargo add tokio --features full

Crates

Crate	Description
`tronz`	Meta-crate re-exporting all sub-crates
`tronz-primitives`	`Address`, `Trx`, `ResourceCode`, signatures
`tronz-signer`	`TronSigner` trait and `LocalSigner`
`tronz-signer-aws`	AWS KMS-backed `AwsSigner` (optional)
`tronz-provider`	Transport, provider, fillers, and domain types
`tronz-contract`	TRC20 / TRC721 bindings and the `tron_sol!` macro

Depending on tronz is the recommended path; the sub-crates are published separately for cases where you need only a subset.

Features

The tronz meta-crate exposes additional functionality behind feature flags so you only compile what you use. default covers the common network, contract, and local-signing path. full also enables mnemonic, keystore, and TIP-712 support; AWS KMS remains opt-in:

Feature	Enables
`default`	TLS gRPC transport, contracts, and local signer
`full`	`default` plus mnemonic, keystore, and TIP-712 support
`provider-grpc-tls`	The provider and gRPC transport with TLS support
`provider-grpc`	The provider and gRPC transport without enabling TLS
`contract`	TRC20 / TRC721 bindings and `tron_sol!`
`signer-local`	`LocalSigner` (included in the default feature set)
`signer-mnemonic`	BIP-39 mnemonic and BIP-44 HD key derivation
`signer-keystore`	Web3 Secret Storage V3 keystore support
`signer-tip712`	TIP-712 typed-data signing
`signer-aws`	AWS KMS-backed `AwsSigner`

For a complete and up-to-date list, see the tronz crate's Cargo.toml.

Supported Rust versions (MSRV)

The minimum supported Rust version is 1.91.1. tronz uses the Rust 2024 edition.

Importing types

The most common types are re-exported at the crate root:

use tronz::{
    Address, Trx, U256,                          // primitives
    LocalSigner, TronSigner,                     // signers
    ProviderBuilder, TronProvider,               // providers
    TRONGRID_MAINNET, TRONGRID_NILE,             // FullNode endpoints
    TRONGRID_MAINNET_SOLIDITY, TRONGRID_NILE_SOLIDITY,
};

Specialized types live in their respective modules — for example tronz::primitives::ResourceCode, tronz::providers::*, and tronz::contract::Trc20Ext.
